Answer:
Susie is 25 years old
Step-by-step explanation:
Let
- x = the age Susie has now.
- x - 20 = the age she was 20 years ago.
If Susie is 5 times the age she was twenty years ago, then
x = 5 . (x - 20)
x = 5x - 100
4x = 100
x = 25
Susie is 25 years old, which is 5 times the age she was 20 years ago (25 years - 20 years = 5 years).
